Black hole in Milky Way

NASA's Swift satellite freshly spotted an increasing wave of high-energy X-rays from a starting place to the middle of our Milky Way galaxy. The explosion, created by an atypical X-ray nova, publicized the occurrence of an earlier strange stellar-mass black hole.

An X-ray nova is short-term X-ray sources that emerge rapidly, achieves its production crest in some days and then become paler out over a time of months. The explosions begin when a gush of gathering gas rapidly runs near one of the densest objects known, moreover a neutron star or a black hole.

The black hole must be a part of a low-mass X-ray binary (LMXB) system, which includes a standard, sun-like star. A flow of gas pours from the ordinary star and come into a storage diskette around the black hole. In most LMXBs, the gas in the disk curves inmost warms up as it top toward the black hole, and makes a stable stream of X-rays.
